I think I've identified a minor issue with using Google Checkout as the payment processor for CiviCRM, but am new to this and don't know whom to tell about it...

Here's the issue and suggested solution:

I recently installed CiviCRM at a host (Dreamhost) where they run PHP as CGI. The post-order callback from Google to googleNotify.php fails with the error:

Fatal error: Call to undefined function getallheaders() in [MY_PATH]/drupal/sites/all/modules/civicrm/CRM/Core/Payment/GoogleIPN.php on line 575

I think the problem is that getallheaders() is not available when PHP is run as CGI. The problem can be resolved by patching GoogleIPN.php by:

1. Define the function emu_getallheaders() somewhere in GoogleIPN.php

from http://forums.digitalpoint.com/showthread.php?p=4768191:
function emu_getallheaders() {
   foreach($_SERVER as $name => $value)
       if(substr($name, 0, 5) == 'HTTP_')
           $headers[str_replace(' ', '-', ucwords(strtolower(str_replace('_', ' ', substr($name, 5)))))] = $value;
   return $headers;
}

2. Replacing the single call to getallheaders() in GoogleIPN.php line 575.

Is this a problem worth addressing, and if so, is this an acceptable solution?
